Install latest Blender to Debian
On Ubuntu, there's a PPA, so you can run the commands in the terminal

sudo add-apt-repository ppa:irie/blender
sudo apt-get update
sudo apt-get install blender


and you'll have one of the latest builds of Blender (read more here or visit the PPA's website here).  WARNING: This won't be the official stable release, but the most recent version of Blender as of a few days ago.

As for Debian, I believe that Ubuntu PPAs can be used on Debian too.  It seems like a bit of work, so hopefully someone else has a better solution.
